williamusco has posted footage of a May 19th sighting of an orb bobbing around a phone line in Houston. This really seems like a bird or something, but it does have a stranger, more fluid way of moving than you'd expect from a bird. It's definitely too big to be an insect, and it's definitely not any time of man-made craft.

Here's the YouTube description:

This video was taken on 5/19/2012 near galleria in houston tx look at the right bottom corner see the ufo moving fast up and down other pictures were taken and clearly you can see several of them
